I always liked the simple look of the Intercom emails - that sort of looks to me like an Instant Message from a team member - so I decided to replicate it in ActiveCampaign for your viewing pleasure.
After installation:
1) Update the goal timings to reflect the fixed countdown dates & launch dates
2) Review the copy in each email provided, and update to make it your own.
3) Update the final goal to correspond to a purchase event - this will make sure that they get pulled out of the automation if they purchase
4) Update the initial trigger to correspond to how someone might enter this flow (can be a list subscription, or form submit, for example).
